DOUBLE SHOVEL PLOW.

- SPECIFICATION forming part of Letters Patent No. 597,045, dated January 1 1, 1898.

Application filed April 24;, 1897. Serial No. 633,657. (No modclfl To all 1071,0112 it may concern:

Be it known that I, CHARLIE BOWMAN WIL- LIAMS, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented certain new and usefulImprovements in Do uble-ShovelPlows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The object of my invention is to provide a double-shovel plow or cultivator which may be readily adjusted to run evenly on a hillside and which may be adapted to the convenience of plowmen of different heights.

My invention consists in certain novel features shown in the accompanying drawings and hereinafter more particularly set forth.

Of the drawings herewith, Figure 1 is a perspective view of a double-shovel plow embodying the novel features of my device. Fig. 2 is a side elevation of my device, showing one of the shovel-beams elevated, as when in actual service on a hillside. Figs. 3 and a are details showing the preferred construction of the slotted iron bar having an angular bend midway its ends, with the ratchets on the vertical arm thereof and the spring-latch which engages in said ratchets, said an gularly-bent bar and spring-latch being material features of my device.

In the drawings, 13 B are the shovel-beams, to which are attached the shovels S S in any well-known manner, the said shovel-beams B B being pivoted together by the pivot-pin p and adapted to operate independently of each other. The shovel-beams B B are provided with the spring-latches Z) 21, consisting of the spring-impelled latch-bars e e and the foot-levers f f and the bolts 0 c, which are adapted to move freely in the slots S S of the vertical arms '2] o of the iron bars A A, each having an angular bend midway its ends. The iron bars A A, each having an angular bend midway its ends, are provided with the ratchets a a, and are attached to the clevis K and adapted to move thereon independently of each other by means of the pivot-pin p,

the clevis K being also mounted on the pivot pin 19. The iron bars A A, each having an angular bend midway its ends, are secured to the handles h h by means of the bolt d and the bolt (1, through which the link L is in turn attached to the handles H H by means of the set-bolt (P. The link L is provided with the notched slot 5-, whereby the set of the handles H 11 may be adjusted by means of the set-bolt d in the usual manner.

The operation of my device is simple, yet effective. In hillside-plowing the great difficulty with the ordinary plow is that the plowman cannot walk between his plow-handles, for in order to make his shovels cut evenly he must be constantly lifting on or depressing one of his plow-handles, thereby necessitating his walking to one side of the plow, and, incidentally, on the plants he is working. This I entirely overcome in my de vice, for, as appears from the foregoing description, the shovels S S are adapted to be raised or lowered independently of each other and fixed in any desired position, which may be readily changed at the will of the plowman. The shovel-beams B being pivoted at p when the plowman retracts the latchbar 6 by pressing his foot against the footlever f the shovel-beam B and the shovel S may be raised or lowered accordingly, as may be desired, by lifting or depressing the handle 11, the vertical arm n of the iron bar having an angular bend midway its ends A being free to move along the bolt 0 by means of the slot S so long as the latch-bar e is retracted from its engagement with the ratchets a. When the shovel-beam B and the shovel "S have been raised or lowered to the desired point, the plowman removes the pressure 011 the foot-lever f, whereupon the latch-bar e is impelled by its actuating-spring in the wellknown manner into engagement with the appropriate ratchet aon the vertical arm 1) of the iron bar having an angular bend midway its ends A, thereby firmly holding the shovelbeam B and the shovel S in the desired position, the shovel-arm B being operative in the same manner and to the same extent.

Another advantage my device possesses is this: My improved double-shovel plow may be readily adapted to plowmen of different heights by raising or lowering both shovelor lowered to conform to the convenience of I the plowman, and from this position either of the shovel-beams may be raised or lowered as circumstances may necessitate, as set forth.

I am aware that Letters Patent No. 405,007 havebeen granted to Elisha Colohil Burnett for improvements in double shovel plows, whereby the shovel-beams move vertically upon each other, and to others for somewhat similar devices; but I am not cognizant that any one has heretofore invented, described, or claimed a double-shovel plow substantially the same or equivalent to my device as set forth. I

What I claim, and desire to secure by Letters Patent of the United States, is-

1. In a double-shovel plow, the combination of'the shovel-beams secured to, but adapted to operate independent-1y of, each other, with iron bars, each having an angular bend midway its ends, also secured to but adapted to operate independently of each other, the shorter arms of said angularly-bent bars projecting vertically; said angularly-bent bars being adj ustably attached to the handles of the plow, and means for firmly engaging said shovelbeams with the vertically-projectin g arms of said angularly-bent bars, and readily disengaging said beams therefrom, substantially as described.

2. In a double'shovel plow, the combination of the shovel-beams, pivoted at their front ends and adapted to actindependently of each other, with iron bars, each having an angular bend midway its ends, also pivoted at their front ends and adapted to act independently of each other, the shorter arms of said angularly-bent bars being approximately vertical and secured at their upper ends to the plowhandles, in any well-known manner, the vertical arms of said angularly-bent bars being provided with a vertical slot engaging bolts through said shovel beams, whereby said shovel-beams may be raised or lowered on said vertical arms of said angularly-bent bars. ratchets on the edges of said vertical arms of said angularly-bent bars, and a spring-latch on each of said shovel-beams adapted to engage in the ratchets on the vertical arm of said an gularly-bent bars, substantially as described.

3. In a double-shovel plow, the combination of the shovel-beams, pivoted together at their front ends and adapted to act independently of each other, and the handle-bars, with iron bars, each having an angular bend midway its ends, also pivoted together at their front ends and adapted to act independently of each other, the shorter arm of said angularly-bent bars extending vertically upward and secured to the handles of the plowin any well-known manner, the front ends of the handle-bars being secured to slotted links, containing longitudinal and notched slots, by a set-bolt of the ordinary form, the lower ends of said slotted links being attached to the horizontal arm of said angularly-bent bars, also by means of a set-bolt, a longitudinal slot in the vertical arm of said angularly-bent bars, bolts projecting laterally through said shovel-beams and engaging the slots in the vertical arms of said angularly-bent bars, ratchets on the outer edge of said angularly-bent bars, and springactuated latches on said shovel-beams adapted to be engaged in, and to be disengaged from, the ratchets in said vertical arms of said angularly-bent bars upon the operation of suitable foot-levers, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLIE BOWMAN WILLIAMS.
